and curve.cpp and surface.cpp contain the rest.
Also get rid of the meshError stuff; will just use the nakedEdges
mechanism for that. And I won't run the interference test
continuously, have added a menu item for that.
[git-p4: depot-paths = "//depot/solvespace/": change = 1934]
triangle join. And add controls to show and hide the solid model
edges (independently of the shaded mesh), and to suppress the
shaded triangles from SVG/EPS output.
[git-p4: depot-paths = "//depot/solvespace/": change = 1932]
export. So I calculate lighting for each triangle in the mesh, make
a BSP, and then traverse it in-order and output those as SVG or
EPS. And I test edges against the mesh, removing those portions of
the edge that overlap a triangle in front of them (using the
kd-tree to accelerate).
[git-p4: depot-paths = "//depot/solvespace/": change = 1931]
use that for surface-line intersections. That has major problems
with the heuristic on when to stop and do Newton polishing.
There's also an issue with all the Newton stuff when surfaces join
tangent.
And update the wishlist to reflect current needs.
[git-p4: depot-paths = "//depot/solvespace/": change = 1925]
fix convergence tolerance so that points projected into a rational
polynomial surface end up much closer than LENGTH_EPS.
[git-p4: depot-paths = "//depot/solvespace/": change = 1906]
the same precedence as sqrt. Add the code to find naked edges, and
draw them highlighted on the model. And make the direction of trim
curves consistent, always ccw with normal toward viewer; so there's
no need to fix the directions before triangulating.
[git-p4: depot-paths = "//depot/solvespace/": change = 1903]
from an extrusion, with piecewise linear trim curves for everything
(that are shared, so that they appear only once for the two
surfaces that each trims). No Boolean operations on them, and the
triangulation is bad, because gl seems to merge collinear edges.
So before going further, I seem to need my own triangulation code.
I have not had great luck in the past, but I can't live without it
now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1899]
corresponding to each param from the Jacobian, and see if it loses
rank. If it does then that one was important, so it's bound. Then
display a big blue square around its point until the next normal
solve.
[git-p4: depot-paths = "//depot/solvespace/": change = 1887]
tables in the code, which I have written in perl and am checking
in.
Also get WM_MOUSELEAVE events from win32, so that I can de-hover
everything when the mouse leaves the graphics window. And fix one
of the icons, which was 23x24 instead of 24x24.
[git-p4: depot-paths = "//depot/solvespace/": change = 1883]
auto-showing when a solve fails. And accept expressions, not just
numbers, for that new dimension value.
[git-p4: depot-paths = "//depot/solvespace/": change = 1877]
just applies an offset to the DXF before exporting. Useful enough
to be worth the ugliness, though.
This is the stupid routines from SketchFlat, slightly reworked.
[git-p4: depot-paths = "//depot/solvespace/": change = 1866]
linear segments to generate, irrespective of the chord tolerance.
That used to be hard-coded, and it needs to be small enough to
avoid lags while working interactively, but I also need to export
fine geometry.
[git-p4: depot-paths = "//depot/solvespace/": change = 1857]
lets us export open curves, if the user drew them that way.
Also increase the limits on how many pwls we will generate for a
single curve.
[git-p4: depot-paths = "//depot/solvespace/": change = 1854]
some magic numbers. This would be trivial to break, but still more
difficult than patching the binary to skip the check...
[git-p4: depot-paths = "//depot/solvespace/": change = 1853]
theorem; it's evaluated as a surface integral over each triangle.
And don't regenerate the emphasized edges unless we have to;
specifically, don't do it when the only dirty group is the
drawing group.
[git-p4: depot-paths = "//depot/solvespace/": change = 1849]
And fix a bug; wasn't asking the user whether to save before
abandoning file when a new file was opened recent.
[git-p4: depot-paths = "//depot/solvespace/": change = 1830]
based on a chord tolerance. And rewrite the pwl circles to work
against a chord tolerance too (which they really were doing before,
but in funny units).
Also make "assemble" combine type do a union after interference
checking; was previously just copying, which meant that coplanar
faces could break subsequent operations.
And make right-clicking effectively toggle shift key, instead of
forcing it on; so you can pan or rotate with either right or middle
button.
[git-p4: depot-paths = "//depot/solvespace/": change = 1829]
where it was, move the export (DXF, PNG, STL) stuff to export.cpp,
and move the regen/solve stuff to generate.cpp.
[git-p4: depot-paths = "//depot/solvespace/": change = 1825]
all coordinates are divided by that number as we export.
And add functions to store a float in the registry. I'm using those
for the scale factor, and also to replace the crazy scaled integers
that I was using for light positions etc. before.
[git-p4: depot-paths = "//depot/solvespace/": change = 1824]
specify the plane from which we want to grab the triangles. Shared
edges are then removed with the same code used to check for
watertight meshes, and the remaining edges are assembled into
polygons.
[git-p4: depot-paths = "//depot/solvespace/": change = 1823]
introduced by the bsp routines. It's usually, though not always,
possible to generate a watertight mesh. The occasions where it's
not look ugly, floating point issues, no quick fix.
And use those to generate a list of edges where two different faces
meet, which I can emphasize for cosmetic reasons (and some UI to
specify whether to do that, and with what color).
And make the right mouse button rotate the model, since that was
previously doing nothing.
[git-p4: depot-paths = "//depot/solvespace/": change = 1821]
that to try to find them if we can't find them by absolute path.
This is intended to make everything still work if you copy an
entire directory tree of files that import each other.
Also add a mechanism to not paint the scene if we're not sure it's
consistent; otherwise got some crashes on startup. And disable both
text and graphic window when displaying a modal dialog, wasn't
doing that always.
[git-p4: depot-paths = "//depot/solvespace/": change = 1808]
separate groups. The section is swept normal to the trajectory,
producing a mesh. I'm doing the triangles only now, not copying
over any entities.
Also fix a bug in the PNG export; rows are 4-aligned, so that was
breaking when the width of the image wasn't divisible by four. Also
fix a bug in lathes, where it generated overlapping triangles for
one segment.
And change the groups to record both "this mesh", the contribution
due to the extrude/lathe/whatever, and the "running mesh", that we
get after applying the requested Boolean op between "this mesh" and
the previous group's "running mesh". I'll use that to make step and
repeats step the mesh too.
[git-p4: depot-paths = "//depot/solvespace/": change = 1801]
that perspective in the gl matrices, and also everywhere that I
check mouse pointer positions against the model, and for the zoom
to fit.
[git-p4: depot-paths = "//depot/solvespace/": change = 1796]
user-visible text. And make points hoverable/selectable even when
GW.showPoints is false, and zoom to fit before regenerating on file
open, because then we're at the right zoom level (and will use the
right pwl tolerance).
[git-p4: depot-paths = "//depot/solvespace/": change = 1788]
to save our registry stuff (because we were calling exit() instead
of doing a PostQuitMessage()), and a misclassification of triangles
coplanar with the test surface, when the test surface contained
zero-area triangles.
[git-p4: depot-paths = "//depot/solvespace/": change = 1773]
using the initial numerical guess of whichever vector is already
known to choose our projection planes.
And add a mechanism to defer showing the text window or
regenerating, in order to simplify dependencies on valid actives.
Also yes/no/cancel when about to abandon an unsaved file, and a
bugfix when rotating a rot/trans point.
[git-p4: depot-paths = "//depot/solvespace/": change = 1772]
becomes dirty when the user makes a change, and only the dirty
groups get solved. That's a huge effective speedup.
Also add delete function for groups. That has an interesting issue;
it actually ends up recursing on GenerateAll(), since GenerateAll()
calls ClearSuper(), ClearSuper() might need to recreate a group (if
all the groups were deleted), and that would activate the group,
which calls GenerateAll. The right solution is probably a deferred
execution mechanism, where you can schedule something to happen
before we go idle, but not do it right now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1771]
in one place. And remove the ability to disable the solver, since
that's unlikely to be anything but confusing (and in any case, was
badly implemented). This is in preparation for selective solving,
of only the dirty groups.
[git-p4: depot-paths = "//depot/solvespace/": change = 1769]
create a `new' stack-allocated instance of an object; just From,

are transformed by a rotation and translation, and appear in the

nicely. And to do that, I've added the user interface to show an
edit control in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1749]
and in the case of a singular Jacobian, report which constraints
can be removed to fix it. Also a mechanism to hover and select
